What a ridiculous statement. The man you call Master lived the Torah, and taught Torah to the people. He spent his time preaching the Torah message of the Kingdom, and never set foot in a church; there were none. The Catholic Church cannot abscond with the entire Bible and then claim that it has the ownership thereof. That’s so dishonest and it’s just silly.
When did Catholics “abscond” with the Old Testament? I’m Catholic educated and no such thing is taught. It is the Jewish Bible - the Torah and we all know that.
That won't stop them from trying, though.
You can’t argue with Catholics on what makes scripture authentic. To a Catholic it’s authentic only because of “tradition” (which ignores that establishing a “tradition” could have been wrong), which leaves it as errant if Catholics did not adopt it. It’s a circular sort of “proof”.
